Definitions

  • the invention relates to equipment and devices used to collect floating objects in the sea, lake or other waters where there is a change of height level usually due to tidal and oscillation changes.
  • the inventor as a hobby, is concerned with nature conservation, and reading various literature and reports has come to the knowledge that there is large pollution of the sea, primarily with plastic, which is a global problem. Namely, once the plastic reaches the sea, it stays in it for a long time, given the long disintegration period for plastics which is approximately 400 years, or according to some expert estimates even more than 1000 years.
  • the inventor has studied known devices and equipment used to collect floating plastic waste in the sea, and has determined that such devices and equipment are in fact large energy consumers.
  • the most common equipment used for cleaning seas and marinas from floating plastic are ships equipped with special floating nets, which is an expensive solution and demands human labor.
  • mini vacuum cleaners operating on the suction principle use their own power-operated pump that sucks the surrounding water surface and are extremely inefficient in terms of energy due to the fact that they need an external source of energy.
  • the inventor is unaware of the existence of a device that would collect floating waste in the sea, based on the use of pure ecological energy due to tidal and oscillation changes.
  • the main advantages of this invention are that it is a simple ecological device and that it is an effective ecological device that is long- lasting and multifunctional.
  • Each individual device as a whole which is the subject of this invention, functions in a very simple principle, utilizing the horizontal and vertical natural forces.
  • Horizontally waves generated naturally and waves caused by the influence of vessels that have the task of inserting the floating plastic objects into the device.
  • Vertical forces are tidal changes that have a function of capturing floating plastic objects in the ecological device during low tides.
  • the floating objects will drift into the device that needs to be placed in a position that is exposed to stronger strikes of waves.
  • the shutter assembly prevents the floating objects out of the unit.
  • the objects fall down with the water level below the lower part of the shutter assembly.
  • the lower element of the shutter assembly is lifted and the floating objects remain trapped beneath the lower element of the shutter assembly. This prevents the floating objects from getting out of the device and thus polluting the environment again.
